DVR-’n’ AUXILIARY STARTER TIMEOUT (n = 2 or 3) (Hydro only)
Description: One of the auxiliary starters did not start properly.
Troubleshooting: On a solid state starter, the DR1 input did not go high within the time pro-
grammed in the UP TO SPEED TIMER parameter (1.0 - 8.0 sec).
DVR-’n’ DOWN NORMAL LIMIT OPEN (n = 2 or 3) (Hydro only)
Description: This message indicates that the car has traveled beyond the bottom terminal landing
and has opened the down normal (directional) terminal switch.
Troubleshooting:
1. Check the location of the car.
2. Check the voltage at terminal DNTD.
3. Check the limit switch connections.
DVR-’n’ DOWN TERMINAL LIMIT FAILURE (n = 2 or 3) (Hydro only)
Description: Both the Down Slow Limit and Down Emergency Limit switches have been detected
to be in opposite states. These switches should open/close simultaneously, meaning that the volt-
age at these terminals should always be identical.
Troubleshooting:
1. Check the connections to terminals DSL1 and DSL2.
2. Check the limit switches for proper operation.
DVR-’n’ DRD (UP TO SPEED) FAILED TO ACTIVATE (n = 2 or 3) (Hydro only)
Description: The DRD input that monitors the UP TO SPEED output from the solid state starter did
not go high when expected.
Troubleshooting:
1. Check the wiring associated with the solid state starter, especially terminal SSD.
2. This message may also be displayed if the UP TO SPEED timer duration is shorter than the
amount of time it takes to ramp the motor up to operating speed.
3. If any faults are displayed on the solid state starter refer to the starter manual.
DVR-’n’ DRD INPUT FAILURE (n = 2 or 3) (Hydro only)
Description: The Delta Redundancy (DRD) input monitors the normally closed auxiliary contact of
the Delta contactor.
Troubleshooting:
1. Verify that the STARTER #1 (2, 3) TYPE parameter setting is correct (see page 5-54). This fault
is generated if the starter is solid-state but the starter type parameter is set to WYE-DELTA.
2. Verify that voltage of the coin shaped battery (CR2032) on the HC-MPU board is about 3Vdc.
3. The wiring or devices connected to DR1 input may not be terminated.
4. Check the Delta auxiliary contact wired to terminal DR1 and replace if necessary.
DVR-’n’ EXCESSIVE NUMBER OF FAILED START ATTEMPTS (n = 2 or 3) (Hydro only)
Description: The starter failed to start after three consecutive attempts.
Troubleshooting: Check the fault log to see what faults were generated when attempting to run
the starter.
DVR-’n’ M2L INPUT FAILURE (n = 2 or 3) (Hydro only)
Description: The M2L input monitors the status of the relay contacts of SAFL and SAFS against the
circuits that drive these relay coils. Bus 2L should be 120VAC and relay SAFL should be picked only
if the doors are locked. 2MV bus must also be active.
Troubleshooting:
1. Check or replace relays SAFL and/or SAFS on the HC-CTL board.
2. Verify that IDC terminal 2L on the HC-CTL board connects to IDC terminal 2L on the HC-DVR
board.
3. Check the thermal overload wiring between terminals TO1 and TO2 on the HC-DVR board.
4. Check the wiring of the starter overload between terminal OL1 and OL2 (if present).
